Title:
COMPRESSOR WITH AIR INTAKE SPRAY COOLER
Document Type and Number:
Japanese Patent JP2015098787
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a compressor including an air intake spray cooler, capable of making a clearance amount between rotor blades and a casing of the compressor close to a target value without restricting a quantity of sprayed water for air intake spray cooling.SOLUTION: A clearance amount δ between a casing 112 and each rotor blade 105 measured or estimated by a measuring instrument 115 is input to a clearance control device 120. If the input clearance amount δ is greater than a target clearance error εref and difference between the clearance amount δ and a target clearance amount δref is greater than the target clearance amount error εref, the clearance control device 120 calculates casing target temperature Tref and a casing-heat-exchanger target heat transfer quantity Qref so that the clearance amount δ is closer to the target value δref. The clearance control device 120 controls a casing heat exchanger 114 to operate on the basis of the calculated values.
